This distribution is documentation-only.
It contains no code for you to run.
Included are various Perl 5 Pod and Perl 6 Pod files describing the Perl 6 language.
For a tool to read this documentation,

Larry Wall started the Apocalypse (latin for revelation) series as a systematic way of answering the RFCs (Request For Comments) that started the design process for Perl 6.
Each Apocalypse corresponds to a chapter in the book Programming Perl,
3rd edition,
and addresses the features relating to that chapter in the book that are likely to change.

Larry addresses each relevant RFC,
and gives reasons why he accepted or rejected various pieces of it.
But each Apocalypse also goes beyond a simple "yes" and "no" response to attack the roots of the problems identified in the RFCs.

Note: These documents are outdated and and will not be updated to match the specification (see "Synopses").

The Synopsis (latin for comparison) started as a fast to read diff between Perl 5 and 6.
Because they are also easier to maintain,
all changes of the language,
that are evolving from the design process are written down here first.
The Apocalypses and Exegeses are frozen as "historic documents".

In other words,
these docs may change slightly or radically.
But the expectation is that they are "very close" to the final shape of Perl 6.

The Synopsis documents are to be taken as the formal specification for Perl 6 implementations,
while still being reference documentation for Perl 6,
like Programming Perl is for Perl 5.

Note that while these documents still being subjected to the rigours of cross-examination through implementation.

These are Pod-ified versions of magazine articles about Perl 6 that have appeared in print during the design process.
Take these with a grain of salt as they might not describe Perl 6 as it is now.
They are mostly from http://www.perl.com and http://www.perl-magazin.de/.
